To all whom it may concern.-

Be it known that I, IsAAo JACKSON TURNER, a subject of the King of Great Britain, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Im rovements in Motor- Wheels, of which the f lowing is a specification.

This invention is characterized by the fact that the vanes or blades tend normally to remain in a common plane at right angles to the axis of rotation and rock or turn upon a joint located at an appropriate distance from the center of motion and from which joint the blades or vanes extend toward the axis of rotation. For some purposes such a wheel may be constructed of a single piece of sheet metal or other material of appropriate strength and resiliency, in which case the blades or vanes may be cut in the form of quadrants, being separated from the body of the disk except at one side adjacent the periphery. When so constructed, the blades tend to lie in the plane of the disk. They will, however, be deflected by the stress of a current of air, steam, water, or other fluid acting upon them in lines parallel with the axis of rotation, the stress of such a current determining the pitch or the amount of flexure at the point of connection of the vane with the body of the disk. It will be apparent, therefore, that the wheel will revolve in the same direction whether the motive power is applied to one face of the disk or the other.

The characteristic of a motor-wheel embodying the ideas of this invention is that the pressure exerted by the motive power upon that part of the vane lying between the rock ing or hinge connection and the axis of rotation is applied at or near the circumference of thewheel with a leverage which would not exist if the vanes were mere blades occupying lines tangential to circles struck from the center of rotation. V

In this application I have shown the invention embodied in the form of a toy windwheel or pin-wheel.

In the accompanying drawings, Figure 1 is a perspective view illustrating the invention; Fig. 2, a front elevation of the wheel; Fig. 3, an edge elevation showing in full and dotted lines the displacement of one of the vanes; Fig. 4, a face elevation of a wheel or disk of a modified construction, and Fig. 5 an edge view thereof.

The disk shown in the several figures may in this case be constructed of cardboard,very light sheet metal, or other suitable materials. It is provided with a hub a, adapted to receive a pin fixed in the end of a handle or rod 1), the mounting being such that the disk may freely rotate. Quadrant-shaped vanes c d e f are formed by cutting the disk, as plainly appears, leaving an uncut portion 9 adjacent the periphery, serving to connect the otherwise detached vanes with the remaining radial parts it of the disk, the part 9 serving as a rocking or hinge connection for the vane. When exposed to a current of air, or on being moved. rapidly through the air, the vanes will be displaced, as indicated by the dotted lines in Fig. 1 and by the full lines and dotted lines in Fig. 3, in which the arrows indicate the directions in which the air-pressure is exerted upon the disk. In Fig. 1 the face of the disk is coated upon segmental areas irrespective of the cuts forming the vanes with elementary colors, which have been indicated. by the numerals l, 2, 3, 4, 5, 6, and 7. Other color schemes or arrangements of color upon the disk may be adopted. The one shown is, however, interesting, as the disk presents the appearance of being white when rapidly rotated.

Fig. 4 shows a modification. The two vanes i j are formed by parallel cuts a j adjacent to and on opposite sides of the center. The behavior of the wheel is the same as already described. In this construction, however, where the material of which the wheel is made is light it is desirable to attach on opposite sides diametrically-arranged strengthening-strips m.
